134 DISKA.SI':S OF I'OUI.TKV. 



On posttnorteiii examination the liver is fonnd 

 shrunken, liardened and marbled or spotted with 

 areas of grayish or yellowish tissue. A microseopic 

 examination shows the liver cells to contain droplets 

 of fat and the liver tissue degenerated and largely re- 

 ]ilaced b}' j-ellow fat globules. 



As the disease is not recognized during life, treat- 

 ment is out of the question. If a number of cases oc- 

 cur in the same flock, give greater variety of food and 

 a run on grass. In addition, bicarbonate of soda may 

 be given in the drinking water to the amount of one 

 or two grains a day for each l)ird. 



FATTY livi:k. 

 It is contended l)y authors who have examined into 

 the subject, that the fatty livers which are so skill- 

 fully developed ])y certain feeders of geese and ducks, 

 and which are considered a great table delicacy should 

 not be confounded withiivers which have undergone 

 fatty degeneration. The latter is a disease while the 

 former is simply a physiological condition. In fatty 

 degeneration tlie liver is shrunken, there is a formation 

 of fat within the cells and destruction of the cells, 

 while in fatty livers the fat is deposited between the 

 microscopic elements of the liver, and this organ is 

 thereby enlarged and rendered more succulent and 

 delicate, but there is no destruction of the cells. If 

 the process of fattening is proi)erly carried out there 

 is, consequently, no disease. 



tuhi-:kcui,osis of the livkr, spleen and 

 peritonf;um. 



This disease is manifested by whitish or j-ellowish- 

 white nodules and aggregations of nodules varying in 

 size from a mere point to an inch or more in diameter.
